BISHOP, CALIFORNIA—An anonymous tip has led to the recovery of a series of 3,500-year-old rock carvings that had been stolen from a sacred Native American site in California’s Sierra Nevada. The carved images of hunters, animals, and geometric designs, which are protected under the Archaeological Resources Protection Act and listed on the National Register of Historic Places, had been sheared off the sides of boulders in an area known as Volcanic Tableland with power saws. No one has been arrested for the crime at this time.
